Pavers Block Characteristics. 5.3.0 The inter locking concrete paver tiles should conform to IS-15658 (LATEST). They shall be tested as per the code and have to qualify limits specified by us down below. 5.3.1 The paver tiles should be made of M-30 (80 mm) design mix concrete in approved size and shape. For acceptance the average of compressive strengths of 8 pavers shall be minimum 3 0 N/mm2 (MPa). Any paver in the tested lot shall not have compressive strength less than 30.1 MPa. If needed, pavers shall be designed and manufactured on higher side to concrete grade M-30 to meet this requirement without extra cost to RAJKOT MUNCIPAL CORPORATION. Testing shall be done as per relevant clauses of IS-15658 (LATEST). 5.3.2 The concrete pavers should have perpendicularities after release from the mould and the same should be retained until the laying. 5.3.3 The surface should be of anti skid and anti glare type. 5.3.4 The paver should have uniform chamfers to facilitate easy drainage of surface run off. 5.3.5 The concrete mix design should be followed of each batch of materials separately and weigh batching plant is to be used to achieve uniformity in strength and quality. 5.3.6 The pavers shall be manufactured in single layer or more to ensure smooth surface on top and to remove all voids. 5.3.7 The pavers shall be of cement Grey colour without any pigment or colored with pigment or with chemically treated top surface as specified. 5.3.8 All paver blocks shall be sound and free of cracks or other visual defects, which will interfere with the proper paving of the unit or impair the strength or performance of the pavement constructed with the paver blocks. 5.3.9 The compressive strength requirement of concrete paver block shall be minimum 30 MPa (N/sqmm) for 28 days (Testing as per IS-15658) after applying the correction factor as per IS-15658 (LATEST). (Please refer clause 3.1 also). 5.4.
